Can someone please help?

Answer 1

1. x+4x

2. 5x

3.
`6(7)/(x)`

4. 4x-2x+15

5.
`(6+x)^2`

Explanation:

To write expressions remember these key words:

• a number is a variable like x
• sum is +
• difference and subtracted is -
• quotient is ÷
• product is ×
• reciprocal means flip like
  `(1)/(9)---> (9)/(1)`
• square is an exponent of 2 like
  `x^2`

1. x+4x

2. 5x

3.
`6(7)/(x)`

Remember a quotient would be
`(x)/(7)`but the reciprocal is
`(7)/(x)`.

4. 4x-2x+15

5.
`(6+x)^2`
